The guy who sold me said it was a kind of carnelian, I don't know but it has a so nice color and seems turtle. And for the shape too it was good for that kind of representation..
I made today some 'new but very ancient' creatures of sea. I'll try to post some shots soon
For the moment many kisses to everybody...

Ciao! So happy you like my tiny stones.. stones wisper what they want to become... and I'm loking forward to hear what they say Benz, the eyes are two carnelian beads Soon more photos.
Kisses from Sicily
